Recoil spring for Star "S" series .380

Hello all!
I have an older "S" series Star .380, and am having a devil of a time finding a replacement recoil spring for it. I tried Numrich, no joy. No luck getting a hold of Bob's gun parts, though he seems to have a ton of Star parts, he won't answer an email.

Can ANYONE help me? Maybe steer me to a recource I haven't looked into, or has a parts gun available? I'd hate to scrap the piece over a recoil spring.
Thanks a ton!
Chris
